EMC – Avoiding the nightmare

Brought to you by The Radio Technology Group

This event will look at Electromagnetic Compatibility (EMC) including design, testing, regulation and diagnostic probing.

About the event

Reliable radio communication devices are essential in today’s world. It is vital that multiple systems can operate without mutual interference, and this is the aim of design for Electromagnetic Compatibility (EMC). Good EMC engineering begins with the design concept and should not be a matter of applying fixes to a complete device that failed to meet specification because of spurious emissions, internal crosstalk, or susceptibility to interference from another device. EMC is designed in, not tested out.

Speakers at this event will share their knowledge on regulations, good practice, countermeasures and measurement.

The event will be a good place for younger engineers to learn, and for mature engineers to share their experience.

The draft agenda aims to cover the following:

  • Emissions regulatory testing
  • Diagnostic probing
  • Magnetic field mapping
  • Automotive requirements
  • EMC CAD software
  • Design for EMC

EMC issues of Wireless products

Roger Ray, Technical Director, RN Electronics

Emissions from wireless devices, are generally understood by wireless designers. ETSI and FCC specifications define the limits for harmonics, in and out of band spurious, and adjacent channel.
However, transmit test modes often don’t allow full configuration or use of product (Ethernet/USB/Serial ports etc. may not be fully functioning) therefore EN 301 489-x series of standards come into play (class B radiated emissions etc.) to cover generic/other emissions. Also conducted port emissions both power and telecom need to be measured if applicable. Other considerations are: Multiple transmitters in the same product, and installing an OEM module. Together with EU tests that are generally defined in standards, and FCC/ISED tests that refer to ANSI standards or KDB’s.

Q&A

Why are there so few Harmonised EMC Standards?

Steve Hayes, Technical Director, Element Materials Technology
There have been very few Harmonised EMC standards issued in recent months. This is due to a fundamental issue identified by the European Commission that is yet resolved that covers the assessment of the product during testing. This presentation will highlight the issues and provide a clear path to approving products against the appropriate directive without the use of harmonised standards.

EMC Simulation of Automotive Ethernet

Dr Tamara Monti, Solution Consultant - Dassault Systèmes /Simulia

Rapidly escalating levels of data rates are projected to grow even further in the future, fueled by trends like the upcoming introduction of connected and autonomous vehicles. This talk will present simulations of EMC related aspects of the automotive Ethernet: the effect of the PCB layout on the emission from an automotive Ethernet channel, crosstalk from the automotive Ethernet channel to other cables inside one harness, and susceptibility of the channel based on the BCI testing method.

RF shielding – A practical demonstration

Mark Tyndall, Senior EMC Engineer, Eurofins York

This demonstration looks at the radio-frequency shielding provided by a typical metallic enclosure and explores how it can be degraded by poor design or unconsidered changes.
